Kindof like "follow the bouncing ball". If you really want to be professional, upgrade to the Pro version so you can also manage a list of singers and keep track of who is Up next! Typically you buy special CDG discs to use for karaoke, which are just like regular CD's except they have graphics in them too, showing you karaoke song lyrics. You Put the CDG into your mac and Play it, or you can "rip" the songs (ie: import them from the CDG onto the mac's hard drive), then you can play them whenever you want even without the CDG. Supports burning* of Mix discs!
